To all whom 'it concern:

Be it known that I, GEORGE W. FRANZ- vHEIM, a citizen of the United States of America, .and resident of'Wheeling, county of Ohio, and State of West Virginia, havel invented certain ynew and useful Improvements 1n Leg-Fastenmgs, of which the following- 1s afspecification.

" 7 v.This invention relates to new and useful imrovements inleg-fastening devices for bath- Y ubs, stoves, and the like; and it has forvits primary object to providey a simple device whereby the legsl of bath-tubs, stoves, and

,wedges, are wholly dispensed with, such eld or maintained in such f other like' bodies may be drawn into pro er keys'. or wedges being open to objection on the ground that they are subject to acciden-l 'tal displacement and render a fastening delscribed, referenceV being herein hadto the vice in which they'are employed more or less unsafe l -With these and'other objects in view, the invention finally consists in. the particular, construction, arrangement and combination 'ofparts which will hereinafter be fully de- -accompanying drawing, forming a part of this specllication, 1n wh1ch- Flgure l 1s alongltndlnal section of a 'portion of a bath-tub and of a'leg attached thereto, illustrating a preferred' embodiment fof my' invention; Fig. 2 is asection of the i, sameon the line 2 2, Fig. 1 Figs.` 3,]t`and '5 areeach views simi-lar to Fig. l, showing 'various modified formations of the legs andof. the lugs carried `byl the tub; F ig# 6 is a detail perspective view, from beneath, of the shown ,in Fig. .5; and Fig. 7 is a view t-silnilar to F-ig. 1, showing still another modif Referring to said drawing, in which-like' designating characters indicate lilteV -parts throughout the several views-'1 indicates the supporting-leg the front 'of which` 1s exitended upwardly to .engage the tub .oit-T stove, having vintegral therewith a rearwardly-extending isubstannually-horizontaltongue 2,

-- LEG-FASTENING.,

Patented l l provided in a lug 5 which is'integral the bottom 6 of the bath-tub, as shown in V Iig. 2; or, -as shown in Figs. 3 and `5, said tongue may be plain, in which. case 1t hes 4, said 'tongue inaybe plain and be lprojected through a loop-likedug 5b carried by the bottom of the tub; or, as shown in Fig. 7, the tongue may be splayed-that is, beveled` from its lower edge toits upper edgeand fit in. the dove-tail groove or mortise 4 of the lug I5. F urthermore,vas shown in Fig. 3, the base of the lug 5a may be horizontally extended to forma bearing for laterally formed wings or projections formed on each side. of the tongue 2.

The tongue may be perfectly plain, as shown in Fig. 7, or it may have an upright lug, ior angular terminal 8, as shown in Figs. l, 3 and 5, or it may have adownturned lug or terminal 8a', as shown in Fig. '-l. In any case, however, a set-screw9 1s rprojected through a threaded hole .in the end or terminal of the tongue and hasits end of the lug carried by the tub, said'screw being directed diagonally against the base portion 10 of the, lug in the constructions illustrated in Figs. l, 3, 'and 7, and downwardly inclined against the edge of the loop-like lug 5" in the construction shown in Fig. l. Said set-screw is preferably provided with a slightly tapered point, as shown. As is apparent, when any of the lconstructions illustrated herein is employed, the set-screw is directed through the threaded hole in the terminal end of the tongue with its point impinging against the lug. As said screw' is tightened the leg isdrawn up to position against the tub; and when said leg is properly seated, the set-screw exerts such a force against said lugthat said leg is 'rigidly held in position, effectually preventing retraction of the tongue.

lVlien properly adjusted, the tub, stove, or other article to which the leg is attached, vmay be moved about ,without danger of the latter beingdisplaced.. Accidental retractionor withdrawal of the set-screw isbut little', if at all, liable to occur, Whereas the usual key .or wedge employed is, 'as experience has proven, subject to such retraction and withdrawal. i

It will be understood that I do vnot claim Dec. 1'?,
